Hi Greg,

After merging the driver-core tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/debugfs/file.c: In function 'debugfs_print_regs32':
fs/debugfs/file.c:560:7: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]

Caused by commit 1a087c6ad975 ("debugfs: add tools to printk 32-bit
registers"). To use readl(), linux/io.h should be included.

I have used the driver-core tree from next-20111118 for today.
